[amsat-bb] Just received UAH ARISS contact - much harder to rx than normal. Arrow antenna problem?

The default is to use the handheld from the Columbus module. In some
cases a mobile rig from the russian segment is used which is much
stronger. The orientation of the ISS and the movements of solar panels
also make a difference. So normally the same radio/antenna combination
as the packet is used, so coverage/signal should be similar.

Which contact are you comparing the signal to (date/time)? What was
the max elevation of that contact and what was your max elevation this
time?

(There is a plan to replace the faulty mobile rig in the colombus
module at some stage)
